Current activities

Dr. Sagar Jain holds the chair of photovoltaics and optoelectronics group and is based in the energy and power theme. His research investigates the fabrication/engineering, integration and characterization of novel materials for emerging Photovoltaics, Solar-thermal , Thermoelectric and Optoelectronics. (these includes but not limited to - Silicon photovoltaics, Perovskite solar cells, Organic photovoltaics, Quantum dot solar cells, Tandem solar cells and Dye solar cells)

He is exploring advanced optoelectronic, spectroscopic (vibrational, HRXPS, UPS, NEXAFS) as well photovoltage characterization techniques to understand structure-property-performance relation in emerging photovoltaics. One of the several domains of his research involves fundamental investigation to minimize the toxicity of these solar cells and using interface engineering approach to improve performance, long-term stability and ultimately upscaling of these novel technologies. The research also involves exploring new application for photovoltaics for instance, photocatalysis (H2 generation), indoor light harvesting for IOT, Space application, Building integrated photovoltaics (BIPV), Application targeted integrated photovoltaics (ATIP) and many more inline.

With Industrial partners he is actively investigating Floating photovoltaics (FPV) and Agrivoltaics (APV) performance , research and development capabilities at Cranfield University.

Presently, he is establishing the scale-up facility for roll-to-roll manufacture of perovskite, dye solar, organic photovoltaics and tandem photovoltaics.
